EX8A is an 8-port 10G EPON card, which can be used in the chassis of Fiberhome brand OLT AN6000-7, AN6000-15, AN6000-17, and AN6000-2. 10G EPON is a point-to-multipoint passive optical network access technology standardized in IEEE 802.3av, which evolved from the EPON standard IEEE 802.3ah. There are two key points in the IEEE 802.3av standard: the uplink and downlink bandwidths specified in IEEE 802.3ah are raised up to 10 Gbit/s; 10G EPON has good compatibility so that 10G EPON ONUs can coexist with EPON ONUs in an ODN. In this way, the operator’s investment is protected.
1. Urban 10G EPON Upgrade in Spain
A Spanish telecom integrated FiberHome EX8A Boards into AN6000-17 OLTs for Madrid’s dense residential and business districts. The 8-port 10G EPON card supported symmetric 10Gbps speeds, delivering ultra-broadband, 8K IPTV, and low-latency cloud services to 1,024 subscribers per board (1:128 splitting ratio). Its compatibility with legacy EPON ONUs protected existing investments, while 20km transmission via PR30/XFP modules covered urban extensions. 1588v2 synchronization ensured high-quality video calls, and Type B/C PON protection (≤50ms switching) minimized downtime—aligning with the operator’s F5G network upgrade strategy.
2. Mixed-Service Convergence in Brazil
A Brazilian ISP deployed EX8A Boards in AN6000-07 OLTs for São Paulo’s suburban mixed-use areas. The card’s asymmetric (1.25Gbps uplink/10Gbps downlink) and symmetric modes flexibly served residential broadband and enterprise cloud needs. With 64 kbit/s DBA granularity, it optimized bandwidth allocation for diverse traffic, while IGMP snooping supported multicast IPTV services. Hot-swappable design and batch ONU configuration simplified maintenance, and FEC function enhanced transmission reliability. This cost-effective solution enabled smooth migration from 1G EPON to 10G EPON without replacing ODN infrastructure.
